20130163087 | GLASS SUBSTRATE COATED WITH AN ANTI-REFLECTIVE LAYER - The invention relates to a coated glass substrate, especially a glass substrate comprising an anti-reflective layer (AR) with improved opto-energetic performances and a good mechanical and chemical durability. The glass substrate according to the invention comprises a glass sheet provided with a porous AR layer comprising a majority of silicon oxide in the form of (i) a sol-gel type matrix and (ii) particles. Advantageously, the AR layer also comprises a quantity of aluminium oxide, expressed in the form of Al2O3, that is more than or equal to 2 weight per cent and less than or equal to 5 weight per cent. Said layer also comprises at least 55 weight per cent of particles and a maximum of 80 weight per cent of particles in relation to the total weight of silicon oxide. | 06-27-2013 |
